Homeostasis

Homeostasis (from Greek: ὅμοιος, homoios, "similar"; and ἵστημι, histēmi, "standing still"; defined by Claude Bernard and later by Walter Bradford Cannon in 1929 + 1932) is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition. Typically used to refer to a living organism, the concept came from that of milieu interieur that was created by Claude Bernard and published in 1865. Multiple dynamic equilibria adjustment and regulation mechanisms make homeostasis possible.
